    Do I need special cable to run outdoor speakers?
    We strongly recommend our direct burial, CL3/FT4 waterproof cable and wire connectors that are designed for the outdoors. Our speaker wire uses a specially formulated UV-resistant, white polyethylene jacket that provides protection against water damage and allows the cables to withstand extreme weather conditions like rain, snow and high temperatures and incorporate twice the insulation of average cable. If you plan to bury the cable, OSD recommends you bury it 4-6" underground so that it's not visible nor pose a danger of somebody tripping over it. Our speaker cable is ideal to use in direct burial applications. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

    Add Volume Controls
    Volume controls can be a great addition to a system providing both proper impedance matching and more hands-on local control of the volume in the listening area. We offer a great selection of outdoor volume controls to choose from!

    Extremely Durable
    OSD outdoor speakers are developed with harsh conditions of the outdoors in mind. Our rock speakers use only non-water-absorbing materials and won't absorb any water. This is critical in winter so it won't freeze and crack. The shape is designed to withstand large amounts of pressure, extreme temperatures and moisture. Remember though, outdoor speakers are an investment, so take care of them. Storing them away from extreme weather conditions will only lengthen the time you will get enjoying outdoor speakers. These rock speakers utilize weather-resistant components for years of trouble free performance.

    What's on your mind?

    Linda Estill • 12/17/2019, 2:17:43 PM We are not tech savvy people. Does the speaker just need to be plugged into an AC outlet? Can I connect via Bluetooth to my android and Kindle?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Linda:The RS850 are our top of the line rock speakers, but it is a passive design that needs a powered (or amplified) signal from an Amplifier or Reciever to play music. We do have another pair of 8.0" passive rock speakers as well, our model RX805, which also needs a powered signal. Thes speakers are the basis of a Bluetooth Rock speaker kit featuring these same speakers; a model BTR-805 (Bluetooth Rock). It features a Master 8.0" Speaker that needs to plug into an AC outlet. Which delivers power to both an internal Bluetooth Receiver and a two-channel stereo amplifier. One channel connects to the inner 8" coaxial (2-way speaker). There is a speaker wire that runs from the Master Speaker to the matching Satellite Speaker (same as a single RX805 rock speaker) carrying the second stereo channel. So your Bluetooth enabled devices (Smartphone or Tablet) connects wirelessly to the Master Speaker's Bluetooth Receiver. The Master and Satellite Speakers should be placed between 8 to 12 feet apart for the best stereo separation.I hope that is not too confusing,
    Anthony DaSilva • 06/13/2021, 3:31:17 AM Are these speakers sold as pairs?

    Hi Anthony: These 8" 2-Way Rocks are sold as each, The RS805 are sold in pairs. TimL
    Cameron • 12/18/2022, 9:58:32 AM I currently have 2 of these and a MX880 amp. I’m looking to add more coverage around my pool. Can I add some of the landscape speakers to this setup? These provide good bass coverage but I’d like to be able to get more sound around the pool without having to raise the volume too high. Thanks.

    I am assuming you have two pairs of RS850 connected to the MX880. One scenario is to have one pair for zone 1 and another for Zone 3. That would leave you with Zone 2 and zone 4. The FORZA6S would be an ideal match with the RS850. Both zone 2 and 4 could power two pairs of FORZA6 Garden landscape Pendants. All four zones are rated at 4-ohm stable. We only recommend driving some of the four zones at 4-ohm, but the max recommendation is to drive the Odd zones at 8 ohms (powering a single pair of RS850) and utilize the Even zones at 4 ohms (up to two pairs per zone). Or drive four pairs of the RS850, one pair per each of the four zones. You have a lot of flexability, it depends on your application. TimL/3-23
    Richard Griggs • 01/07/2024, 11:28:13 AM I am looking to connect a pair of these OSD RS850 speakers as well as 2 Polk Atrium 8 speakers to my Sonos Amp (150W). Will this work?
    Customer Service • 01/09/2024, 5:26:33 PM
    Hi Richard: No problem in connecting two pair of 8-ohm speakers (OSD850 and the Polk Atrium 8) in Parallel. The SONOS is stable down to a 4-ohm load. TL
